Be a known that 1, ,LEANDER J; Macon.

' MICK, ofvOhieago, in the county of. Cook and :State of Illinois, haveinvented certain newi and usefullmprovementsinAutomatic Grain; BindingMechanism, ofwhich thefollowing is 'a spe'cification. i 5 1 e The first.partof my invention more 'esp'e; cially relates to that class ofautomatic grainbinders in which the" bindingwmechanism is mounted upon atraversing carriagaas in the f Well-known Withington binder built byGLYH,"

86 L. J. McCormick at Chicago, Illinois. u f

.In thismachine the binding mechanism is i adjustable to suit thevarying length ofgra'in,

sofas always to bind the gavel in the middle by mechanism operated bythe driver from his seat,\as shown, for instance, in LettersPatent no.174,454, granted to said Withingtonl March 7,1876. j

The objects of thisfipart otmy invention are to simplify theconstruction of this adjust ifng .mechanism, and to adjust .the bindingmechanism automatically at the will of the driver by the same powerwhioh aetuates the y 1 The next part of my invention relates to thewire-supply i n g mechanism of the binder. Its Objects are,'whilesecuring a free delivery of thebinding-wire, to maintain a uniform pressure upon it, notwithstanding variations in the size of the spool uponwhich itis wound, and also to prevent the wire flying from the spoolinfcase the wire should break. These ends I attain by combining awire-spool having pro .1 .jecting axles or trunnions with slotted sup-"lporting arms or brackets'pinwhich slots the trunnions traverse andturn,- a skeleton frame secured upon said arms-beneath thet'runnions. ofthe sp0ol,,and'a flexible; band stretched across said frame, upon whichband the periplie I [cry of the wire coil rests as hereinafter more 1fully set forth.

the gavel.

flhe object of this branch of my impltv mentis' to allow great freedomof movement tofthe spring-arm of the compressor, so asjto preventitsbinding or straining, which ends Iattain by combining a binding orwirecairryingarrn' vibratin g on a suitable pivotor'support intermediateof its length, a compressing, arm also vibrating or swinging on asuitable support, a slottedribbed head mounted on the heel-extensionofthe binder-arm, a connecting rodor link pivoted on the compressor andi passingfthrough the slotted head, anda spiral Y spring encircling theconnectingrod between the compressor-arm and the slotted-liead,as

in the bestway nowknown to me.

T helaccompanying drawings represent all f myimprovements as embodied inone machine ious y, T

however, some of them may be used without the others, and in machinesdifi'ering some,-- what inthe details of their construction in thoseherein sh0wn.- l Figural represents a planorftopview of so .niu'ch'of abinding-machineembracing my im. i provementasjisnecessary to illustrate;the subj ect-ma'tterherein claimed, with thebinderarm andcoinpressorelevated. {Fig.2 r p e. sen'ts aside'elevation of the same, and F ig..3

Fig.15 represents averticalsec- .tion. through the wire-spooland its tension on the line 2 2 of Fig. 1. Fig. 6 represents afront Viewof the binding-a'rm and compressor inflthe act of closing. Fig. 7represents a vertical longitudinal section, on the line 3 3 of Fig. 8,

through the slotted head in which the connecting or compressor rodslides. Fig 8 represents atop view of the same head, and Fig.

9' represents a transverse vertical section The mechanism is shown asmounted ,upon 1 stout} frame, A, capable of attachment'to' the ordinaryharvester-frame in the usual wellknown ways.

An adjustable frame, B C, rests upon this frame and is movable thereon,being held down by suitable hooks b b, embracing the stationary frame A,and prevented from lateral displacement by a guide-rail, b Figs. 1, 2,and 9 I prefer to make the portion 0 0f the adjustable frame, at least,of metal, and provide it with ways 0 0, upon which the reciprocatingbinder-carriage D slides. A long shaft, E, turning in fixed hearings inthe stationary frame A, turns loosely in journals or pipe-box bearings c0 upon the sliding frame, which is capable of moving freely endwise uponthe shaft. A sprocket or other suitable driving Wheel, F, driven in anyof the usual well-known ways from the harvester itself, carries aspurwheel, F, which gears into a corresponding pinion, g, capable ofsliding freely upon a shaft, It, and controlled by a shipping-lever, G,of usual wellknown construction. A worm, H, mounted upon the shaft h,gears into a spur-pinion, I, turning on a shaft, i, mounted on asuitable bracket secured to the frame. A crank-arm, I, on this pinion ispin-jointed to one end of a link-rod or pitman, J, the other end ofwhich is connected with a stud, a, depending from the adjustable frame0.

By this mode of construction, when this mechanism is thrown into gear,the crank-arm I rotates and moves the frame 0 backward or forward,carrying the binding-carriage with it,

thus adjusting the wire to the middle of the grain lying upon theplatform, and adapting the binding mechanism to different lengths ofgrain but the adjustment, it will be observed, is made in eitherdirection by the continuous rotation of the driving-shaft in onedirection, the direction or length of adjustment being dependent uponthe length of time the gear continues to operate.

When thrown out of gear the machine, of course, rests in the positionwhere it is left at the moment of disengagement.

The advantages of this arrangement are obvious, as the adjustment isautomatically effected by the gearing, which can readily be stopped orstarted by the hand or foot of the driver without compelling him toexert his strength to adjust the binding mechanism.

The shaft E is secured to the frame A by means of a yoke-plate, whichembraces a collar on the shaft, and thus prevents it from movingendwise, while leaving it free to turn. The removal of this platepermits the shaft to be withdrawn, so that the binding-frame can readilybe removed from its supporting-frame. (See Fig. 4.)

Awire-spool, K, is provided with projecting axles or trunnions Ic,capable of turning freely and moving up and down in vertical slots inbracket-arms or supports k, mounted upon the binder-carriage. A skeletonframe, L, is secured upon and encompasses the bracket-arms below thespool-axles. (See Figs. 1, 2, and 3.)

Abelt or strip ofleather, rubber, or other suitable flexible or yieldingmaterial is stretched across the frame L in such manner that theperiphery of the wire-coil itself always rests upon this band, the reeldescendingin its slots for this purpose as the coil of wire diminishesin diameter. The pressure of the wire and its spool upon the belt causesit to sag somewhat and conform to an increased portion of thecircumference of H the wire coil, thus creatin g additional friction. Aconstant friction is thus exerted upon the wire to prevent its payingout too rapidly, and the flying or uucoilin g of the wire, in case ofbreakage, is also prevented.

A vibrating binding'arm, M, is mounted upon a rock'shaft, M, turning inbearings in the binding-frame, substantially as in the Within gtonpatent above mentioned, and as shown and described in Letters Patent ofthe United States of Wm. it. Baker, dated May 22, 187 7 No. 190,096. Aheel or arm, m, projecting beyond the back of "the axis of oscillationof the binding-arm, carries a sliding headfln, slotted vertically andprovided with inwardlyprojeeting ribs or pins, as shown in Figs.7 and 8.

A compressor-arm, O, swings around its pivot 0 on a projecting portionof the bindercarriage.

A spring-arm or link-rod, N, pin-jointedat one end to the compressor ata point intermediate of its length, passes through theslotted head aabove mentioned. This rod is encircled by a coiled spring tending topress it outward in the position shown in Fig. 3. When the compressorand binding-arm are retracted the spring is uncompressed; but when thearm M descends to compress the gavel it compresses the spring, as shownin Fig. 6, and causes the compressor to squeeze the gavel tightly, butwith an elastic pressure, while being bound. With the exception of theslotted head, the above-described mechanism for compressing the gavel issubstantially the same as that shown and described in thebefore-mentioned patent of Wm. R. Baker, and is not claimed by me.

By the above-described construction of the slotted head, the spring-rodN is allowedfree angular play or rocking motion therein, as well asendwise movement therethrough, with-. out the necessity of pivoting thehead, or causing it to swivel, as in the said Bakers patent.

It is deemed unnecessary to describe in dc tail the other parts of themechanism, as they form no part of the subject-matter herein claimed,and are, for the greater part, fully shown in Bakers and Withingtonspatents, before mentioned.

I do not broadly claim binding mechanism adjustable backward or forwardby gearing adapted to be thrown into or out of connection with aconstantly-moving portion of the gearing of the machine; nor, broadly,the combi nation of a traction-wheel, shifting binding mechanism, andintermediate mechanism adapted to effect the adjustment of-fthe bind-iring mechanism by the traction of the wheel;

nor, broadly, the combination of adjustable bindin g mechanism,driving-gearin g, and intermediate connectingmechanism whereby thebinding mechanism may besadjusted in either direction by gearingrotating in one direetion; Ibut limit my claim to thespecificorganization of the above-mentioned devices, hereinbefore setforth.-

Neither do I claim a traveling binding-carriage carrying a binder-armupon an overhanging bracket, and gathering and binding the grain as itreciprocates.

Neither do I broadly claim a grain-receiving platform having wayscombined with a bindtraverses, the pitman or link-rod pivoted to theadjustable frame, the crank pivoted to the :link-rod, the spur-pinion bywhich the crank. is driven, the worm-wheel driving the pinion,

and the gearing driving the worm-wheel.

- 2. The combination of the bracket-arms,

self-adjusting wire-spool with projecting axles. resting in slots in thebracket-arms, the skel- 'eton frame secured upon said arms beneath theaxles of the spool, and the fiexible band stretched across said frameand supporting the weight of the wire coil, these members bein gconstructed and operating as hereinbefore set forth.

3 The combination of the slotted ribbed head n, the spring-rodmovingendwise therethrough and having a sidewise or rocking motionindependently thereof, the vibrating binding-arm, to the heel-extensionof which said slotted head is secured, and the swinging compressor-arm,to which the spring-rod is pivoted, thesemembers being constructed'andoperating as set forth.
